REPLY TO NOTICE OF VIOLATION NRC Inspection Report 98-04 describes a violation where Nonh Atlantic did not take action to promptly determine the status of the A and D steam generator steam pressure protection channels. North Atlantic's response to this violation is presented below.

s.

1. Description of the Violation:

'

The following is a restatement of the violation:

10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, states, in part, that measures shall be implemented to ensure that conditions adverse to quality are promptly identified.

l l

l Contrary to the above, on May 4,1998, NAESCO did not take action to promptly identify l whether steam pressure protection channels for the A and D steam generators were operable, !

after three of the six steam pressure protection channels for the B and C steam generators were found to be inoperable. Subsequent testing determined that two of the six A and D steam generator pressure protection channels v'ere inoperable.

This is a Severity Level IV Violation (Supplement 1).

2. Reply to the Notice of Violation:

Reason for the Violation North Atlantic agrees with the violation. On April 27, 1998, North Atlantic commenced calib' ration activities for six (three each on the B and C steam generators) steam generator l pressure protection channels. On May 1,1998, the lead / lag value for three channels were found l outside of the acceptability limits specified in the calibration procedures. The three channels were calibrated and returned to service. On May 4,1998, North Atlantic determined that the lead / lag values addressed in the calibration procedures were Technical Specification allowable l values and, as such, the as-found data was outside the Technical Specification limits.

An Adverse Condition Report (ACR) was initiated and the event was determined to require a

-

l License Event Report (LER) pursuant to 10CFR50.73(a)(2)(i) due to the operation of the plant l

from May 1,1998 to May 4,1998 in a condition prohibited by the Technical Specifications.

North Atlantic submitted LER 98-005-00 on May 29,1998.

-

On May 1,1998, Station management requested Maintenance personnel to investigate the applicability of this condition on the A and D steam generators. This was not acted upon

-

l promptly. Additionally, the individuals involved in the preparation and review of the ACR did not recognize that the out of tolerance condition identified on the B and C steam generators should have called into question the adequacy of similar channel calibrations performed on the A and D steam generators. By May 4,1998, North Atlantic had not pursued the validation of the i status of similar channels on the A and D steam generators in a timely manner. In addition, Page 1 of 2 1 . , -

,e . .  !

. .  :

i

when the ACR was discussed during the daily Station meeting on May 5,1998, insufficient l

'

information was presented regarding the potential for the condition to be common to the other steam generators and as a result the operability of the A and D steam generators was not pursued' >

promptly.  !

!

This event was included in the scope of a comprehensivbreview of lead / lag issues. North !

Atlantic performed a thorough review of the calibration methodologies used to determine NLL !

card time constants. This review was proactive and involved forming an event team, consulting l with vendors and bench top testing.

The cause of this event is that the Corrective Action System was not effectively implemented ,

'

after the initiation of the ACR. There was not adequate communication between the departments regarding the specifics of the channel calibration failures and the potential for common failures - l was not adequately questioned / pursued. As a result, action was not promptly initiated to validate ,

the status of the A and D steam generators in a timely manner. l

!

Corrective Actions

!

1. The individuals involved in initiating and reviewing this Adverse Condition Report have l been coached and counseled.  !

Date When Comoliance Will Be Achieved i

!

North Atlantic is currently in compliance with 10 CFR 50 Appendix B, Criterion XVI

" Corrective Action."
